这是iphone的屏幕截图,这里阴影非常好但是当我在ipad上运行应用程序时就变成了这样......
现在这个问题我想让它像ipad上的第一张图片一样..
我正在使用此代码删除阴影
extension UIView {
// OUTPUT 1
func dropShadow(scale: Bool = true) {
layer.masksToBounds = false
layer.shadowColor = UIColor.black.cgColor
layer.shadowOpacity = 0.5
layer.shadowOffset = CGSize(width: -1, height: 1)
layer.shadowRadius = 1
layer.shadowPath = UIBezierPath(rect: bounds).cgPath
layer.shouldRasterize = true
layer.rasterizationScale = scale ? UIScreen.main.scale : 1
}
// OUTPUT 2
func dropShadow(color: UIColor, opacity: Float = 0.5, offSet: CGSize, radius: CGFloat = 1, scale: Bool = true) {
layer.masksToBounds = false
layer.shadowColor = color.cgColor
layer.shadowOpacity = opacity
layer.shadowOffset = offSet
layer.shadowRadius = radius
layer.shadowPath = UIBezierPath(rect: self.bounds).cgPath
layer.shouldRasterize = true
layer.rasterizationScale = scale ? UIScreen.main.scale : 1
}
}
使用此行在任何视图上删除阴影
shadowView.dropShadow(color: .black, opacity: 0.7, offSet: CGSize(width: -1, height: 1), radius: 5, scale: true)
任何人都知道问题出在哪里。??
提前感谢:)

问题是当视图布局不正确时你正在使用bounds值。
在viewDidLayoutSubviews中设置阴影。别忘了打电话给super.didlayoutsubviews()
或者你可以致电
view.layoutIfNeeded()
